Abstract: A frame member has two spaced apart parallel rings that are fixed to one another. Each of the spaced apart parallel rings has a pedestal with a notch therein at an edge of the pedestal adjacent a space separating the parallel rings. The pedestals and notches are circumferentially aligned and cooperate to provide a seat for seating a spherical ornamental article therein. A securing member secures the spherical ornamental article to the frame member. The securing member is a ring inserted in the space between the parallel rings of the frame member in a movable manner and is provided with a non-arcuate portion that is complementary to and secures the spherical ornamental article seated in the pedestals and notches of the frame member when the non-arcuate portion of the securing member is aligned with the pedestals and notches of the frame member.

Abstract: A frame member has two spaced apart parallel rings that are fixed to one another at a first location. At a second location diametrically opposed to the first location of the spaced apart parallel rings provide a seat for an ornamental article. A securing ring is disposed in the space between the parallel rings of the frame member and is fixed to the frame member by a pivot pin that is located nearer to the second location than to the first location. The securing ring is provided with a rigid wire that is aligned with the securing ring and is configured complimentary to a surface of the ornamental article for securing the ornamental article on the seat of the frame member. The securing ring pivots about the pivot pin to allow placement of the ornamental article on the seat and the removal of the ornamental article from the seat.

Abstract: A frame member has two spaced apart parallel rings that are fixed to one another only at a first location. At a second location diametrically opposed to the first location each of the spaced apart parallel rings has a pedestal with a notch therein at an edge of the pedestal adjacent a space separating the parallel rings. The pedestals and notches are circumferentially aligned to cooperate with one another to provide a seat for seating an ornamental article therein. The securing member secures the ornamental article to the frame member. The securing member is a ring inserted in the space between the parallel rings of the frame member in a movable manner and is provided with a means for securing the ornamental article seated in the pedestals and notches of the frame member when the means for securing is aligned with the pedestals and notches of the frame member.

Abstract: A method for detecting the presence of a coating material, particularly an organic solderability preservative, such as imidazole, on a copper substrate includes placing a test droplet on the surface of the substrate, forming an image of the droplet and measuring the contact angle between the wall of the droplet and the surface of the substrate.
